DETAILED DESCRIPTION

Referring to FIGS. 1 and 2, a flexible container 10 includes a pouch 12 having a pair of flexible sidewalls 14, 16 that are joined along a side edge 18 by a fin flange 20. The fin flange 20 is disposed to allow a user to grasp and tilt the flexible container 10 to pour contents, such as baby formula, from a pour spout 22 at an opposite side edge 24 of the container 10. In one embodiment, the fin flange 20 is integrally formed with the flexible sidewalls 14, 16. In another embodiments, the fin flange 20 is separately formed and attached to the side edge 18.

The container 10 includes a fill opening 26 at the top of the container 10 and a reclosable seal 28 that is attached to the sidewalls 14, 16. The reclosable seal 28 can be opened, e.g., to place content within the pouch through the fill opening 26 and closed, e.g., to seal the content within the pouch 12 from the atmosphere. A suitable reclosable seal is a rib and groove seal, for example such as a ZIPLOC® brand closure available from SC Johnson and Son, Inc. Single-use seals (e.g., a rupturable heat seal or membrane) may be employed as an alternative to a reclosable seal, e.g., in embodiments where the container 10 is a single-use container (i.e., a disposable container).

The container 10 can be self-standing. By “self-standing”, we mean that the container 10, once filled to a selected level, is capable of supporting itself in an upright, standing position. Extending between the sidewalls 14, 16 at a bottom 30 of the pouch 12 is a gusset 32. The gusset 32 aids in supporting the container 10 in the upright, standing position, when filled.

As noted above, the fin flange 20 allows a user to grasp and tilt the container 10 to pour contents placed within the pouch 12. The fin flange 20 extends along the side edge 18 from the reclosable seal 28 to the bottom 30 of the pouch 12. In one embodiment, the fin flange 20 is formed of two sheets that are joined along a periphery 21 of the fin flange 20. In other cases, the sheets are joined only along the side edge 18. The fin flange 20 includes a graspable region 34 that has sufficient width W and length L to allow a user to grasp and handle the container 10 with the user's fingers. As shown, the graspable region 34 is disposed along the fin flange 20 to allow the user to grasp the fin flange at a location nearer the bottom 30 of the pouch 12 than the reclosable seal 28. In other words, the graspable region 34 is disposed to allow grasping of the graspable region 34 at an elevation along the pouch 12 that is at most about half the height H measured between the bottom of the pouch 12 to the reclosable seal 28. Extending from a surface 38 of the fin flange 20 within the graspable region 34 are an array of projections 39 that provide a texturized surface for enhanced graspability. The graspable region 34 is positioned to allow grasping at an elevation along the pouch 12 that is at most half the height H. The container 10 can then be tilted with sufficient support, using only the fin flange 20, to allow contents to be poured from the spout 22 and into, for example, a baby bottle 23.

With continued reference to FIG. 1, the spout 22 is formed by the sidewalls 14, 16 and is located above the reclosable seal 28. The spout 22 aids in controllably pouring the contents from the pouch 12 through the fill opening 26. In one embodiment, the spout is integrally formed with the sidewalls 14, 16.

The flexible container 10 can include a writing surface 36 disposed between the reclosable seal 28 and the top of the container 10. Permanently printed on the writing surface 36 are regions for indicating desirable information, such as date, time and name, for example. The writing surface 36 can allow printing thereon by a pen, marker, pencil and/or crayon, as examples. The writing surface 36 can also be formed to allow erasable marking, using a dry erase marker, for example. Horizontal markings forming a graduated scale 38 can be permanently printed on the sidewall 14, to provide visual indication of content in the pouch 12. As shown, the scale 38 can display the volume of a liquid placed in the pouch 12 in ounces and milliliters.

Referring now to FIGS. 3 and 4, a self-standing, flexible container 40 includes a pour spout 42 that is located below a reclosable seal 28 and separate from a fill opening 44. The container 40 includes many of the features described above with reference to FIGS. 1 and 2. Unlike the container 10 described above, however, the reclosable seal 28 need not be opened to pour contents from the pour spout 42 due to the location of the spout 42.

Pour spout 42 is formed by sidewalls 14, 16 of the flexible container 40. The pour spout 42 includes a frangible region 46 for tearing and opening the pour spout 42, e.g., to allow for pouring of contents therethrough. Prior to tearing along the frangible region 46, the pour spout 42 is sealed (e.g., during formation of the container 40) to inhibit egress of contents from pouch 12.

The container 40 can be filled through the fill opening 44 and the contents can be dispensed through the spout 42. As above, the container 40 includes a fin flange 20 having a graspable region 46 extending from the reclosable seal 28 toward a bottom 48 of the pouch 12 for grasping and tilting the container 40.

Referring to FIG. 5, a flexible container 50 is shown having tabs 52, 53 to facilitate grasping and retaining of sidewalls 54, 56, when the container 50 is placed within a bottle (as shown in FIGS. 13 and 14. With specific reference to FIG. 13, tab 52 can be formed to extend beyond an opening 102 of the bottle 100 when the container 50 is inserted into the bottle 100 so that the user may grasp the tab 52 and fold the sidewalls 54 and 56 over opening 102 and outer surface 104 of the bottle 100. A cap 106 having a nipple 107 (FIG. 14) and a threaded inner circumference can be secured to the bottle opening 102 having a threaded outer circumference and over the sidewalls 54, 56. The container 50 also includes a frangible region 58 for tearing and removing a portion of the sidewall 54 and 56, e.g., located outside the bottle 100.

Referring again to FIG. 5, the container 50 includes many of the features of the container 10 of FIG. 1, including the reclosable seal 28, pour spout 22, gusset 32 and fin flange 20. Extending along the length of the fin flange 20 is a frangible tear line 60, e.g., for removing the fin flange 20 from side edge 62. Removing the fin flange 20 may be desirable prior to placing the container 50 within a bottle or other container (i.e., when the container 50 is to be used as a liner). The fin flange 20 can also be folded proximate the sidewall 54 or 56 as an alternative to removing the fin flange 20.

The container also includes a spout frangible tear line 64 for tearing the sidewalls 54, 56 above the reclosable seal 28, e.g., to form a spout contour similar to the spout 22 of FIG. 1. In another embodiment, tab 66, shown in phantom, extends upward to a height substantially greater than the height of the spout 22.

Referring now to FIG. 6, a flexible container 70 includes, in addition to features of the container 50 of FIG. 5, a bifurcated pouch including separate compartments 72 and 74 having a seal 76 to provide a sealed barrier therebetween. In some embodiments, the seal 76 is reclosable (e.g., a rib and groove closure) or the closure may be a rupturable membrane or other type of single-use, rupturable seal. Positioned at a fill opening 78 of the container 70 is a second seal 80 (e.g., a reclosable or single-use seal) spaced-apart and extending generally parallel to seal 76. The second seal 80 can seal compartment 74 from the atmosphere. Extending between the seals 76 and 80 is a frangible region 82 for tearing and removing an upper portion of sidewalls 84, 86. As shown, the frangible region 82 is contoured to form a pour spout similar to the pour spout 22 of FIG. 1. However, the frangible region can be of any desirable contour including a line extending 30 generally parallel to the seals 76, 80.

Multi-compartment containers, such as the container of FIG. 6, may be desirable where the contents and container are to be placed in a relatively harsh environment such as within a freezer or in boiling water, as examples, to seal isolate pouring surfaces from the harsh environment. For example, prior to sealing the compartments 72 and 74, the content, such as baby formula, can be placed in compartment 72 and seals 76 and 80 (or only seal 80) can be formed and/or closed and then the container 70 can be placed in the freezer, e.g., to freeze the contents for storage. The container 70 can thereafter be removed from the freezer and the sidewalls 84, 86 can be torn along frangible region 82 to remove material exposed to the freezer air (i.e., the material between seal 80 and fill opening 78). Because seal 80 is air-tight, inner surfaces between the seals 76 and 80 remain unexposed to the cool air trapped within the freezer, e.g., so that the contents are not exposed to surfaces exposed to the freezer air during pouring, for example.

As another example, the container 70 can hold contents within each of compartments 72 and 74, the seal 76 maintaining separation of the contents while the seal 76 is closed. For example, compartment 74 can hold a pre-measured amount of powdered baby formula, while compartment 72 contains a pre-measured amount of liquid to be mixed with the powder to form, e.g., a single serving or pre-selected amount of servings of baby formula. To separate or break seal 76, e.g., without opening or breaking seal 80, a pull tab 90 extends from each of the sidewalls 84 and 86 to aid in pulling the sidewalls away from each other to break or open the seal 76. Once the seal 76 is opened, the powdered contents within compartment 74 are allowed to fall into the liquid contents of compartment 74 and mix within compartment 72. Fin flange 20 can then be grasped, as described above, to tilt and pour the mixed contents from the container. Or, in some embodiments and as noted with reference to FIG. 5, the container 70 may be used as a liner for, e.g., a disposable bottle. Accordingly, the container 70 can separately store mixable constituents that can readably and neatly be combined for use.

FIGS. 7-10 illustrate container embodiments having a compartmented fin flange. Referring to FIG. 7, container 92 includes, along with features described above with reference to FIG. 1, a fin flange 94 (shown in section) having a single, inflated (e.g., with air or liquid) chamber 96. By inflating chamber 96, the rigidity and functionality of the fin flange 94 can be increased. The fin flange 94 can extend along the entire length of side edge 98, above the reclosable seal 28. Extending across the width of sidewalls 97 and 99 and also across the width of the fin flange 94 is a frangible region 101 for tearing and removing an upper portion of the sidewalls and the fin flange. Additionally, by tearing through the fin flange 94, fluid trapped within the chamber 96 can escape from the chamber to allow the fin flange to deflate. In some cases, the user may simply puncture the fin flange 94 to release fluid contained within the chamber to deflate the fin flange. Deflating the fin flange can allow the container 92 to be used as a liner as above with reference to FIG. 5, for example. In some embodiments, the fin flange 94 may extend along only a portion of the length of the side edge 98 (shown by dotted lines). As shown by FIGS. 8 and 9, illustrating container 150, the chamber 96 can be spaced from the side edge 98. In some embodiments, as shown by container 120 of FIG. 10, the fin flange 94 may include multiple chambers 122 and 124 to provide additional rigidity and functionality. The multiple chambers may be in fluid communication with each other or they may be isolated (as shown).

The containers described above can be formed of a single sheet (or multiple sheets) of film of any suitable material including, e.g. high density polyethylene (HDPE), low density polyethylene (LDPE), polypropylene (PP), etc. Suitable materials include food grade materials, e.g., to form container embodiments suitable for food storage.

A number of embodiments of the invention have been described. Nevertheless, it will be understood that various modifications may be made without departing from the spirit and scope of the invention. For example, referring to FIGS. 11 and 12, other indication means can be used such as punch tabs 126 along the sidewall 128, 130 between the fill opening 44 and the reclosable seal 28. The tabs can be labeled with suitable alphanumeric information to denote the date of content storage, for example. Accordingly, other embodiments are within the scope of the following claims.
